To (all whom it may concern:

Be it known that'I, citizen of the United States, residing at l airmont, in the county of ll'larion and State of West Virginia, have invented certain new and useful Improvements in Glass-Heating Burners, of which the following .is a specification.

The present invention relates to means for heating the ends of tumblers or glasses after the some have been cracked of? and ground to melt the same and provide a smooth surface. I

' An important object of the invention is to provide novel heating; means of the above mentioned character, which will. properly melt the ends of the tumblers or glasses without discoloring them. further object of the invention is to provide heating means of the above men tioned character. which is well adapted to he used in connection with a rotatable structure which carries tumblers or glasses.

A further object of the invention is to provide a device of the above mentioned character, which is simple in construction, cheap to manufacture, and durable.

Other objects and advantages of the invention will. be apparent during the course of the following description.

In the accompanying drawings forming" a part of this speeificatiod and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side view of the device, shown in connection with means to move the articles to be heated, Fig. 2 is a plan view of my impiioved heating means or burner, and, Fig. 3 is a vertical sectional view taken on line 33 of Fig. 2, parts being shown in elevation.

In the drawings wherein for the purpose of illustration, 1 have shown a preferred embodiment of my invention, the numeral. 4 designates a stationary support or base, upon which is mounted a stationary upstanding shaft 5.

Mounted upon the base i is a stationary ring 6.

The numeral 7 designates a plurality of spindies which are rotated about the ring 6 and have slidable engagement. therewith.

The spindles 7 are rotatably mounted through brackets 8, which straddle pinions 9, rigidly attached to the spindles. These brackets areprovided near their lower ends with inwardly extending radial arms 10,

which are connected with a gear 11. The gear 11 is rotatably mounted upon the stationary shaft 5.

The numeral 12 designates a stationary gear which is rigidly connected with the shaft 5 and engages the pinions 9. The gear ll'receives its rotation from a gear 13, which is rigidly connected with an upstanding rotatable shaft 14. This rotatable shaft is journaled through portions of the base 4 and carries a wormwheel 15, as shown. The worm-wheel 15 is driven by a worm 16, which is rotated by a motor 17. It is thus seen that when the motor 17 is in operation, the gear 13 will rotate the gear 11, which causes the spindles 7 to rotate about the stationary ring 6, said pinions also rotating upon their longitudinal axes by virtue of the fact that the pinions 9 travel in engage ment wit-h the stationary gear 12. Rigidly connected with the upper ends of the spindles 7 are trays 18 or the like, which are placed the tumblers or glasses to be heated. Disposed inwardly of the trays 18 is a.,cylinder 19, which may be formed of fire-brick or other heat resisting material.

Disposed above the trays 18 and suitably spaced from the same is a substantially semi-annular relatively large burner 20, which is in the form of a conduit with both ends thereof closed, as shown. This burner conduit is preferably formed square in vertical cross-section, as shown, and is provided apon its lower horizontal fiat, wall with perforations 21, which are distributed over the entire area of said wall. Attention is called to the fact that these perforations are comparatively small and that there is agreat numberof them. The numeral 22 designates a gaseous fuel receiving shell, which is approximately relatively large semi-cylindrical; Connected with this shell-2 are pipes 23, which are radially disposed and have suitable connection with the conduit 20, at equi-distantly spaced points as shown. Attention is called to the fact. th t there is agreat number of these pipes 23, which is an important feature of the invention, as by this means alone can the gaseous fuel be properly supplied to the burner conduit-20; so that a flame may be had-which will not discolor the articles of glass to be heated. Connected with the pipes 23 are valves 24-, which allow the gaseous fuel to be properly adjusted in each.

upon

The numeral 25 designates an air supply pipe, which leads into the shell 22. Extending into the pipe 25 is a gas supply pipe 26, which is provided with perforations 27. The pipes 25 and 26 supply air and gas respectively to the'shell 2, wherein a properly carbureted gas is formed, to be subsequently discharged through the pipes 23.

In the operation of the machine the tumblers 28 are placed in the trays 18 as the same rotate past the rear portion of the machine. These tumblers are now front portion of the machine and under the burner conduit 20. The gas escaping through ably hot flame which will properly melt the ground end of the tumbler by the time the same is moved beneath the burner conduit 20 for the entire length. of the same, Without in any way discoloring the glass.

1 am aware that attempts have heretofore been made to construct burners for this pur pose out of clay or other plastic material. These burners are very objectional for many easons, particularly as they crack from being overheated and do not last long. As far as I am aware no burners of this type have heretofore been constructed of iron or any other suitable metal, owing to the factthat these burners when constructed of metal. would discolor the glass. I have discovered that by the peculiar construction of my burner, particularly the provision of the large number of perforations in the burner conduit and the large number of supply pipes, that my burner may be advantageously employed to heat the tumblers without discoloring them.

I wish it understood that the form of my nvention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape,

carried past the the perforations 21 provides-a suitsize, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus claim:-

In apparatus of the character described, the combination with an approximately semi-annular relatively large metallic burner conduit having a substantially horizontal flat bottom wall provided With relatively fine perforations, of a plurality of fuel supply conduits connected with one side of the approximately semi-annular metallic burner conduit and leading into the same at substantially equi-distantly spaced points to supply gas therein for maintaining a uniform pressure of the gas throughout all portions of the burner conduit, a fuel supply chamber arranged substantially concentric with relation to the approximately semi-annular metallic burner conduit and connected with the fuel supply conduits, means for supplying air to the fuel supply chamber, means to supply gas to the fuel supply chamber, a bodily rotatable carrier arranged near and below the approximately semi-annular burner conduit, a plurality of devices connected with the bodily rotatable carrier to move therewith and hold tumblers or the like below and in proximity to the perforated bottom wall of the metallic burner conduit, and means to rotate the described my invention, I

devices upon their longitudinal axes during their bodily rotation with the carrier.

in testimony whereof ailix my signature in presence of two witnesses.
